• Separately adjustable setpoints
• Separately adjustable delay functions (0.1 to 30 s)
• Output: 2 x 8 A relay SPDT
• For mounting on DIN-rail in accordance with
DIN/EN 50 022
• 45 mm Euronorm housing
• LED indication for relays, alarm and power supply ON
Product Description 
Ordering key DPC 02 D M48
3-phase or 3-phase+neutral line voltage monitoring relays for phase sequence, phase loss, over and under voltage (separately adjustable set points), over and under frequency with built-in time delay function.
Supply ranges from 208 to
690 VAC covered by four multivoltage relays. The main application is for gen- erator sets.
